Trinity River Hatchery Area Channel Rehabilitation Project and Gravel
Introduction

The Trinity River Restoration Program (TRRP) has been working with the
Bureau of Reclamation, the U.S. Forest Service (both members of the
Trinity Management Council), and other TRRP partners for several years
to plan and implement placement of coarse sediment (1/4 to 5 inch
diameter gravel) immediately downstream of Lewiston Dam near the Trinity
River Hatchery.  This is one of several gravel augmentation sites
identified in the Trinity River Flow Evaluation Report and the December
19, 2000 Record of Decision where the river channel has degraded and is
in immediate need of additional coarse sediment input.  Post project
improvements in river substrate and hydrodynamics will increase useable
spawning habitat as well as spawning and egg incubation success, and
will provide quality nursery habitat to increase survival of recently
emerged egg sack fry and juvenile steelhead and salmon.  

Implementation of the project will include: [1] removal of existing
riparian vegetation along the riverbank to access the project site, [2]
excavation, redistribution and/or removal of approximately 6,900 cubic
yards of existing riverbed and bank material, [3] mechanically
re-shaping the river channel, including lateral channel widening of
specific segments, [4] introduction and placement of approximately 5,100
cubic yards of washed coarse material originating from the Trinity River
basin, and [5] maintaining levels of coarse material into the future at
this site as needed and provided funding is available.  Excavated
material will be moved up-slope to build a vehicle turn-around and
parking lot for anglers.
  
The Finding of No Significant Impact (FONSI) was signed on May 31,
2006, by the Program's Executive Director, thus allowing the Forest
Service to immediately proceed with the project as described in the EA. 
The (1) the Forest Service EA, (2) additions to meet National
Environmental Policy Act and Reclamation environmental compliance
guidelines, and (3) a memorandum that details the circumstances
surrounding the need for adoption of the Forest Service EA, were
collectively adopted as an EA that meets all of Reclamation's
requirements.  This EA supports signature of the May 31 Reclamation
FONSI. .  

The FONSI and the TRRP's EA are available for public review at
Reclamation's Mid Pacific website at-
http://www.usbr.gov/mp/nepa/nepa_projdetails.cfm?Project_ID=2220 
and will be available June 7 on the TRRP's website at:
